Quick rounded corners in Photoshop

While I’m not a designer, I do need to pop open Photoshop on a regular basis and save off graphics or make small changes. I often need to create a rounded corner rectangle when processing customer logos for theming and I never remember how to do it quickly. This tutorial shows the best method I’ve seen yet and also taught me a neat feature in Photoshop: Edit > Copy Merged. It’s like flattening the image and then copying the current selection which is a major time saver and much safer than flattening, copying and undoing the flatten.
